' also position to the square tubular holes 33, these ness, is provided with a flange 55 on its inner edge and a flange 56 on its outer edge for engaging the portion of the punching device to be described below. Frame 54 is rovided with holes corresponding in 8, and adapted to fit over the heel portion when secured to the shoe. One of these parts is designated 60 and the other 61, .and

they are similarly'connected toithe forward portion of the fralme 54:Wh611 either one is employed, that is to say, projections 62 and 62, as the case, maybe, fit into apertures 63 formed in the transverse member 64 of frame 54.

- Arms 66 and 67 are formed on opposite ends of frame 54 and have pivotal connection with frame members 10 by means of" bolts 68 and 69, the latter being removably mounted so as to permit of the disconnection of the: portions indicated.

The punching device employed in connec tion with the present construction is formed 1n the manner now to be descrlbed.

This device is" employed for punching the holes in the leather around the margin. of the upper for the accommodation of the threadedsockets 41. A metallic plate 70about one inch long isformed with curved sides, said sides being flanged as shown at 71 for embracing the fiangcs' of the frame. 5& The device must be of such sizeas to permit it to slide alon the toe portion of the frame mentioned. Plate .70 is provided with a central aperture through which a tubular device 72 passes, this tube beingresiliently mountedby means of a spiral spring 73 for the purpose of holding the tube downwardly so that it will pass into the apertures of the frame and protrude at the bottom as shown. The purpose of this device 72 is. to guide the punch in the apertures of the frame, thereby centerin the punch with reference to the central line of the threaded sockets 41.- The tubular member 72 fits the apertures of the frame .ac;ura tely,' and the punch fits thecentra-l aperture of member (2 in a similar manner. In order to facilitate the centering of the punch in the "hole it is made self-adjusting by cutting away the lower portion of m' niber 72 at an angle so that when the punching device asa whole is passing along the frame, the spring 73. holding i the member 72 downwardly, the

- tendency will be for the angular portion'to punching device is advanced.

The frame 54: with the smooth heel por-' The punch proper is designated 75 and is tapered at its lower end and threaded at its upper end as indicated at, 7.6 topermit of the ready removal of, the device when worn. v

"The punch is operated by means of a lever 77 pivoted at 7 8 on an arm 7 9 carriedfat one end of plate 70, said lever passing be-' tween fork members 79 formed on an arm 80 connected with the opposite end of plate 70. A longitudinalslot 81' rovides means for mounting a spring 82 earin 'on the underside of lever 77 for returnlng itto normal position after operation. Lever77' is provided with" a'slot 88 through which passes a pin 85 mounted in ears 86 supported on an annular member 87 in which the punch 1s mounted.-

Theshoe is assembled in the following manner:

The threaded sockets 41 are. dropped within the tubular portions 33, so'that they v will rest on hammers 40. The inner sole is then'placed on the last, this sole being already provided with holes for the accomj-l moda-tion of the threaded sockets], TheuP- per, not shown in the 'drawings, -is placed.

in position and secured,-'theclamps l5 and 4:9.being employed for 'forming the; leather around the toe and heel in perfect shape;

After securing the upper the :clamps' just 18." After the sockets have entered the apertures provided for them, the frame 54.

is released at the heel, portion," and a rubber gasket 90 is placed in position, and then the sole 96, the heel portion 91 being attached thereto. The frame 54 is then again locked in position but with the strap portion .61 connected,;and the last .is agaln set up "by means of nut 22. Screws 94am then inserted in the holes in frame54, the screws being of such size that the heads will be -ad' mitted through the holes inthe frame 54.; j

Thescrews can be set up bymeans'of a ratchet screw driver, or any similar tool permitting the rapid operation. 1 No effort is required for this operation, as the sole is alreadyzpressed as much aspossible against the upper.v 1 The ,shoe is-then1finished with.

the exception ofthe wearingparts described in my Patent ferred to.

What is claimed is:

1. In a device ofthe class described, a I" I shell constituting alast and having guiding;

7 means formed in one portion thereof, a plate movable within the shell, a spindle having threaded connectionwith the plate,devices for independently moving the. shell and plate vertically on the spindle, hammers carried by the plate and cooperating with the guiding means, and means for clamping an upper in position on the last.

2. In a device of the class described, a shell constituting a last and having apertured guiding means formed in the bottom thereof,

a plate movable vertically within the shell, a spindle having threaded connection with I the plate, devices for independently moving the shell and plate vertically on the spindle,

and hammers carried thereby and spaced to correspond with the aforesaid A apertured guiding means. I

p 3. In a device of the class described, a shell constituting an inverted last and having guiding means depending therefrom, said guiding means comprising a plurality of tubular members extending continuously around; the outer edge of the last, a device movable vertically within the shell, hammers carried by the device last named and proportioned to enter the tubularmembers, means for forcing sa1d devlce upwardly, and means.

for adjustably mounting the las 4. In a device of the class described, an inverted shell constituting a last and having tubular guiding means depending therefrom, a plate movable within the shell, hammers carried by the plate and each positioned for supporting a threaded socket within the tubular guiding means, a spindle for supporting said plate and forcing it upwardly, and means for moving the last vertically with reference to the spindle.

5. Ina device of the class described, a shell constituting a last, a plate member forming the bottom of the last, said plate having guiding means formed thereon, a plate movable within the last, hammers carried by the plate last named, and means comprising a frame havlng apertures formed therein registering with the guiding means, said frame being adapted to extend along the bottom of the last and conforming thereto at its outer edges.

6. In a device of the class described, a shell constituting a last and including a bottom member, tubular guiding means carried by said member, a plate, hammers carried by the plate and spaced at distances corresponding with the spacing of th guiding members, means for forcing the plate upwardly, and a frame provided with apertures spaced to vcorrespond with the spacing of the guiding means, and adapted to retain. the edges of an upper in position on the last.
